Bar splice for woven wire fabrics



K. E. PEILER A 19, 1930, BAR SPLICE FOR WOVEN WIRE FABRICS R 17,774

entor A lid?! E. Pei/er Reissued Aug. 19, 1930 UNITED STATES My invention relates to sectional wovenwire fabrics, and its object is to provide novel and efiective means for connecting the panels or sections of conveyor belts for-med Ii of sections composed of intermeshing helical wires of right-hand twist alternating with sections composed of intermeshing helical wires of left-hand twist.

Conveyor belts composed of wovenewire 1 fabric are frequently made in sections altern'ately of right and left-hand twist so as to avoid the tendency of such a conveyor to creep laterally upon its supportswhen in use. According to my present invention, I join the "edges of such sections together by means of a bar or strip of metal or other suitable material having a series of perforations adapted to engage the convolutions of aright-hand wound helical wire and another series of perforations adapted to engage the convolutions of a left-hand helical wire. The perforations of the two series are preferably staggered with respect to one another so as to maintain the convolutions of the two wires in substan- 95 tial alinement lengthwise of the fabric and of the sections of fabric that are so joined.

In the accompanying drawing:

' ber constructed in accordance with my invention, showing portions of adjacent woven wire sections which are connected thereby;

Fig. 2 is a longitudinal sectional View taken on the line 2 -2 in Fig. 1; and

Fig. 3 is a transverse sectional view taken on the line 33 inFig. 1. 3 y

In the drawing, the numeral 2 indicates part of a section of-wire fabric composed of wires having right-hand twist, and .the numeral 3 indicates part of a section composed of wires having left-hand twist. A connecting or splice bar 4 joins the end wires 5 and the bar 4 is provided with openings arranged in two longitudinal series 7 and 8. These openings arepreferably parallel and are inclined to interengage properly with the loops ofthe adjacent wires. The openings 7 and 8 are staggered with respect to one another, as shown in thereby to maintain in alinement the edges.

Fig. 1 is a plan view of a connecting mem- 6 of the sections 2 and 3. For this purpose,

of the wires 5 and 6 are in substantial alinement lengthwise of the fabric. I

Fig. 2 shows the manner in which the open-' lngs may be drilled in the bar i. The inclinat1on of these openings from the vertical forms a good bearing for the portions of the wires which passthrou'gh the openings 7 and 8. It is preferred that the openings 7 and 8 be countersunk on both sides of the bar, as shown 1n F1g. 2, in order that the openings may adapt themselves readily to the curvedsurfaces of the wires.

In connecting sections of woven wire fabric by means of the splice bar described above, I prefer to employ the method described in the patent of John-C. Anderson, granted Nov. 13, 1928, No. 1,691,507, whereby the sections t-o-be joined are laid on opposite sides of the connector, which in this instance is the splice bar' 4, then on one side there is screwed into the right-hand woven section, and into the adjacent series of openings '1,

' a helical wire of right-hand twist exactly like the other right-hand wires composing this section. By a similar operation, the left-hand wound section is joined to the connecting bar, and'the ends of-the connecting wires are bent over in the same manner as the ends of i one another.. Also, it is to be noted that the 1 bar connectors-are of no greater thickness wire fabric, so that when a conveyor belt is made up of woven wire sections connected by such bars,

pass between driving rolls without being ob-' the conveyor is readily able to j than the adjacent convolutions of the-woven:

1 claim as my invention: 7 V

1. A connector fpr joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a member having a series of openings for engaging the convolutions of the right-hand woven wire and also having another series of openings for engaging the convolutions of the left-hand woven wire.

2. A connector for joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a bar having two longitudinal series of openings, one series for engaging the right-hand woven wire and the other for engaging the lefthand woven wire, the openings of the two series being staggered with respect to one another, so as to maintain the convolutions of the two wires in substantial alinement in a direction perpendicular to said bar.

3. A connector for joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a bar havinga longitudinal series of openings inclined for engagement withconvolutions of the right-hand helical wire and having another longitudinal series of similarly inclined openings for engagement with the convolutions of the lefthand helical wire.

4. A connector for joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a bar having two longitudinal series of openings, the openings of one series extending obliquely through the bar for engagement with the,

convolutions of the right-hand helical wire, and theopeningslof the other series extending obliquely through the bar and parallel to the openings of the first-named'series for engagement with the convolutions of the left-hand helical wire, the openings of the two series being staggered with respect to.

one another, so as to maintain the convolutions of the said wires in substantial alinement in a direction perpendicular to said bar.

5 A connector for joining a wire wound in right-hand convolutions to a wirewound in left-hand convolutions, comprising a bar having two longitudinal series of openings, the openings of one series extending oblique: 1y through the bar for engagement with the convolutions of the right-hand helical wire, and the openings of the other series extending obliquely through the bar and parallel t-o'the openings of the first-named series for engagement with 'the convolutions of the left-hand helical wire, the openings of the two series being'staggered with respect to one another, so asito maintain the convolutions of the said wires in substantial alinement in a direction perpendicular to said bar,

and the said openings being countersunk longitudinally and laterally with respect to said bar.

7. A connector bar for joining a wire wound in right-hand convolutions to a wire wound in left-hand convolutions, comprising a fiat integral bar pierced with a plurality of openings distributed longitudinally of the bar and adapted to receive convolutions of said wires and to position said wires both longitudinally and laterally with respect to said bar, the said bar being not materially thicker than the thickness of said convolutions, so that a conveyor fabric made up of panels of such wires connected by such bars will pass between conveyor driving rolls without interferenceuby said bars. v
